title: [Role of female genotype in manifestation of dominant lethal mutations induced by thiophosphamide in the spermatids of male rats].
abstract: Hybrid male mice FICD2 were injected intraperitoneally with thioTEPA at a dose of 1.5 mg/kg or 2.0 mg/kg. During the second week after the treatment males were mated with females of 101/HY, C57BL/6JY and CBA/LacY strains, and embryoic mortality was studied on 3.5 day of pregnancy cytologically and on 15-17 days -- by the dominant lethal method. ThioTEPA did not affect the rate of fertilization. The dominant lethals frequencies differed significantly in females 101 (67%), B6 (59%) and CBA (43%). It is suggested that the differences observed are due to different activity of repair systems in oocytes of females of these strains.
